IPv6 stop working

[gorip96]

Hi

I'm running PPPoE on Nest router, and suddenly in the last few days, IPv6 stops working, I got confirmation from the ISP that they indeed sending IPv6 prefixes to me, but somehow it's not working on my Nest

Anybody having the same issue?

Thanks

Hi @Jeff 

sorry I overlooked this thread, yes the issue still persists, and I think the IPv6 issue is somehow related to the random reboot issue

I’m currently still on 14150.43.80

Hi, gorip96.

I saw your message in another thread, but I want to keep this one going as well. So we're looking into possible issues now. I'm speaking with some internal teams on this and we're checking to see if there is indeed an issue with IPv6. If you have any more details about how it's affecting you, feel free to share that here.

Thanks.

Hi @Jeff 

Basically this what happens :

1. At first, my router ISP is set to bridge, then the Nest is doing the PPPoE towards the ISP, and everything works fine

2. Suddenly I realize that IPv6 stops working, and I notice that the issue starts around the time that 14150.43.80 is released

3. other than IPv6 stops working, my system starts acting up, I keep losing wifi connection multiple times a day

4. I reset the Nest to factory , and it’s not getting IPv6, and the drops still happening 

5. I ask the ISP to change the router config to NAT mode, then reset my nest to use DHCP on WAN, and it still doesn’t help

6. then I saw another thread about using google DNS, I config my system using Google’s IPv4 and IPv6 DNS, but the instability issue is still there

7. Then i reconfig the Nest again only using 8.8.8.8 and 8.8.4.4 and make sure IPv6 is disable, and the system stops losing connection randomly 

so this is why I’m concluding that IPv6 is completely broken, and I believe changing the DNS to IPv4 DNS only is a  temporary workaround, because I’m sure the default setting is using both IPv4 and IPv6 DNS, and anything related to IPv6 is causing the issue

Thanks for the detailed response, gorip96.

It definitely feels isolated to IPv6. I'll pass word along to our internal teams and see what I can glean from them on this. I'll report back when I have more to share.

Thanks.

Hi @EdwardT 

my concern remains, about the IPv6 not working

I started to doubt my self that the IPv6 stopped working is somehow related to the instability/random offline that many people are experiencing 

as I already disable everything related to IPv6, but the instability remains

but yes, enabling IPv6 does make things worse, so my concern on IPv6 remains

thanks
